To aZZ whom it may concern:

Be it known that 1, JOHN JAMES, a citi- Zenof the United States, residing at WVheat-' of Oklahoma,

land, in the county of have invented certain; new and useful Improvements in Grain-Shock Elevators, of which the following is a specifieation, reference being had to the drawings hereto annexed.

Machines of this class commonly consist of a supporting vehicle with teeth or other suitable gathering extremities projecting J forward from it in position toslide under a shock of grain as the machine travels forward, means being also included in the max chine for elevating the grain from the teeth or other gathering means onto a wagon or other transporting vehicle. A machine hav- 'ing a traveling frame-work supported by 2Z0 ground wheels and having 'forwardly-eX- tending gathering-teeth adapted to slide along the ground under a shock of grain'is shown in Letters Patent No. 915,183, issued to me on'the 16 day of March, 1909. This machine .also includes a slatted elevator which extends upward and rearwardfrom the rear. ends of the gathering-teeth, and

in addition. to this elevator one or more toothed rakes, carried at their ends by endless. chain belts, are provided to insure movement of the grain from the gathering- "teeth up said elevator.

A- disadvantage found in a machine of this class-is that the shock of grain, in its intact body, frequently chokes and strains the raking and elevating mechanism, and when delivered by the latter to the wagon it is in too great bulk to be handled by the person attending the loading; D

An object, therefore, of the invention is to overcome this difficulty, and in so doing improved means are provided for disintegrating the shock during the time it is being acted upon by the machine.

Other objects and advantages of the 1nventi'on will be vset forth in the ensuing d esc ription.

Referring to. the drawings, which show an'embodiment-of the invention in practical 'form:Figure 1 is a plan viewof the machine, the left-hand end of the figure being the front. Fig. 2 is a left-hand side elevation. Fig. 3 is a rear elevation, with many. of the parts omitted iii-front of the line Oklahoma and State A-A of Fig.' 2. Fig. 4 is a plan view of the machine, with much of the upper structure removed.

Referring to of which like characters of reference designate like parts, the machine shown in this instance includes a supporting frame 5 whlch lies in a horizontal plane, the rear end of this frame being carried by ground wheels 6 on each side, while the front end 1s supported by a single wheel 7 whose straddl ng fork'8 has fifth-wheel connection with said frame to allow the machine to be guided. A series of curved gathering teeth 9 proect forward from the front of the frame 5, in position to slide along the ground under a shock 10 of grain,a transverse shaft 11 being common toand extended through the rear portions of all said teeth and supported by lugs 12 secured to the front end the several figures, in all to receivethe pivot-shaft 11, a wooden bar 13 being common to and extended through the front ends of said wooden members 9 to aline said teeth and insure their concerted movement.

In order to raise the gathering teeth 9 from the ground out of gathering position, a shaft 14: is journaled transversely in the front end of the frame 5, and is provided with forwardly-projecting arms 15, these arms being connected to said teeth 9 rearwardly of their pivotshaft 11 by links 16.

This shaft 14: is alsoprovided with an arm.

17' which is connected by a rod 18 to a lever 19, this lever being provided with a suitable locking-quadrant 20 and being within easy reach of an operator in the seat 21 for raising and lowering the teeth 9.

In further arrangement, an elevator, which includes two separated chutes 22, extends upward and rearward from near the pivotal point of the teeth 9 .at the front end of the frame 5, the central portions of these chutes being supported by a light frame 25 resting upon the frame 5 while their upper rear ends are, --supported by strap-metal arms 24 which connect to columns 25' on the rear of said'frame 5. leach chute22 comprises a bottom-26 and sideboards 2?, the side-boards projecting about instance. a

A shaft 28, carryingsprocket-pulleys 29., 1s common to and passes transver'sely 5 through ,the 'wooden portions 9 of the teeth 9 in 'frontof the pivot-shaft '11-, while a similar shaft 30,, carrying sprocket pulleys 31, .is journaled across the upper rear ends 'of the chutes 22. i6

In completing the chutes 22 into-an ele- 'vator, a series of link belts 32 are arranged to travel-upon the pulleys 29 and 81 of the shafts 28' and 30, and the ascending 'portionsof said belts travel upon the upper surfaces of the chute bottoms 26.

. A transverse conveyer chute 33 is arranged horizontally under the upper or deliveryend of the-elevator chutes 22, and supported from the main frame 5 by columns 34; and 2 the columns 25, this chutecomprising a bot tom 35 and side-boards 36 and 37. Through the receiving end' of this chute 33, a shaft 38. is journaled fore-and-aft of the machine,. and a similar shaft 39 is likewise 30urnaled 25 through the opposite or-delivery end of said chute, .eachofthese shafts carrying sprocket pulleys 40 with endless link belts 41 traveling upon them. 4

A lateral elevator chute 42,-having 'a bot- 39 tom 43 with side-boards i4, is pivoted to the right-hand columns 25 and 34:, just below the delivery end of the conveyer chute 33, this chute 42 having a shaft is journaled through it coincident with its point of pivot, and a 35 similar shaft 456 journaled through its free.

or delivery'end. These shafts 4'5 and- 46 are provided with sprocket pulleys 47, with end? less :link belts 48 arranged to. travel upon them. 1

hand columns 25 and 34:.

Being an automobile structure, the machine is provided with an engine 50 to propel it, this engine being mounted on the rear of the frame5. The usual shaft 51 is journaled 50 across the frame 5, and is operatively connected with the groiind wheels 6' by link belts 52. This shaft51 is providedwith a gear-wheel 53 which receives motion from a; pinion 5% on the crank-shaft 55 of the engine in the usual way. 7 j

The link belts 32 of the chutes 22 are driven by their upper shaft 30; andpin driv- 'ing this shaft a sprocket pulley 56 on it receives motion through a link belt 5,? from a similar pulley 58 on a counter-shaft 59 journaled in bearings 60 depending from the side-boards 27 of the chutes22. This counter-shaft 59, in turn, has a sprocket pulley 61 which receives motion through a link belt 62 from a similar pulley-63 on the crankshaft equally above below, said bottom in'this 5 The ue'viitor' three 42 is an up in the de- I .55 er engine. as linlr' the lair the the shaft 38 of saidchute; and in driving this shaft a sprocket pulley 64% on it receives motion through a link belt 65 from a similar.

. transverse conveyer chute- .33. aredriven by pulley 66 (in the shaft 67 whichffcommonly extends rearward and-revolves as a necessary member man engine of the class used for this purpose; The link belts as of'the-ele- ,vator chute 42' arejdriven by the shaft 45 of said chute; and in driving this shaft a sprocket pulley on -it receives 'm'otion' through a link belt69from a similarp-ulley 70 onthe shaft 8'8aforesaid; All the link belts of the chutes are provided at intervals with spikesor fingerS'ZI to engage the grain;

Withthese raking-fr'ame's 75 thus-carried by the crank-shaft 72-and"radius-bars- 7-6, their forward portions and the raking-teeth 78 carried thereby will be given araking zmovement that. will tear the shock 10 apart and forcibly} draw it from the gathering lo drive the crankshaft 72,.a sprocket wheel 79 is mounted upon it centrally of the width ofthei machine, and motion isirnparted to this wheel 79 through a link belt 80 from a 'sprocket'wheel 81 on the shaft 51 aforesaid. Toj'clearthis beltEO, and to afford the operator a viewforwardin driving the machine, the two chutes 22 are spaced a considerable distance apart, as bestshown in Fig- 1.. I

The dividing action of the stop 82 retards movement of the shock I!) from the gathering" teeth 9 onto the chutes 22' and thereby holds the shock under the action of the raking-frames 75,

with the result that the grain is delivered by themachin'e to the transporting vehicle in a disintegrated condition and a more even pply for loading.
